I will try to get some photos to help with this, but I am looking for some advice.
I just pulled the floor out of my 1990 Supra Sunsport as there were a few soft spots (all in spots NOT above the stringers) to find some mixed results. The stringers are all 95% structurally sound. The only places where there were some issues were where there was wood attached to the stringers running perpendicular to the length of the boat that had started to rot. A small amount of this made it to the stringers running parallel with the length of the boat but nothing too deep before finding very solid wood.
We then spoke with a well-respected local shop that gave us some advice. We were told that the "damage" to the stringers was very minimal and that the stringers that mattered (that the engine was attached to) were in great shape, so not to worry. He said that if we wanted to, we could clean up the few little spots on the stringers, add some support, glass or epoxy it, add some foam, put a new floor on, and be good to go for many years to come. He did say that since we had done so much work already, he would charge $1,500 to replace the stringers, but he said it really was not necessary. What are your opinions?
Do the repairs that he mentions seem reasonable and effective? Do you agree with his recommendations? Where do you find and how difficult is it to apply the fiberglass over the wood? My father is a wood worker and I have been around it my whole life so that does not concern me, but I am just trying to figure out how effective it would be...
Thank you all SO much for any feedback you can supply!
